help for a newbie

Hi I'm kinda like a newbie so I was wondering if any one could help me with designs for making a pneumatic cannon. If anyone feels like helping then it would be greatly appreciated. Thanks.

start by telling us the general shape you want it to be, then size, then tell us what valves you want..

so we know what to tell you

i sudjest you use a selenoid valve because it is cheaper and easier to use than a ball valve plus it shoots farther. it looks hard to install but its actually really easy
